【摘要】 气候舒适性是人居环境评价的主要组成部分。为探索甘肃省主要城市人居气候舒适性,根据31个城市1971年～2008年日照时数、风速、气温、相对湿度等气候因子的月平均值,对温湿指数、风寒指数、着衣指数及由此3指数组成的气候舒适度进行了计算分析。温室指数计算结果表明,河西走廊及陇东地区的城市,感觉非常舒服的时间为1个月,极冷时间为3个月;甘南高原的城市全年无感觉非常舒服的时间,极冷月份为5～6月;陇东南南部城市无感觉非常舒服的时间,北部有2个月感觉非常舒服的时间,感觉极冷的时间为3～4月。气候舒适度计算结果显示,除甘南高原的城市外,甘肃省各主要城市候舒适度都比较高,大部分城市最舒适居住时间都在5个月以上,其中舒适度较高的城市为陇东南南部的武都、文县及北部的天水,其次为陇东地区、中部地区及河西走廊地区的城市。甘南高原地区的城市舒适度较低。各城市夏季气候舒适度最高,处于舒适水平。冬季气候舒适度最低,处于不舒适水平。春、秋季气候舒适度基本一致,大部分城市处于较舒适水平。更多还原

【Abstract】 Climate is an important part of human settle environment. To study the climate suitability of major cities in Gansu,based on the meteorological data such as sunshine,wind speed,temperature,relative humidity sec. in 31 cities ,the thermal humidity index(THI),wind chill Index(WCI),index of clothing(ICL) and degree of climate comfort-ability that composed by THI,WCI and ICL in these cities had been calculated and analyzed. The results of THI indicated that the very comfortable period was one month and the freezing period were three months in the cities located in Hexi corridor and the east of Gansu. There was no very comfortable period and the freezing period were five to six months in the cities located in Gannan plateau. There was one month very comfortable period in the cities that located in the north of Southeast and no very comfortable period in the cities that located in the south of Southeast of Gansu and the freezing period were three to four months in this region. The results of human habit climate comfortable-ability showed that the most human climate habit comfortable periods distributed in the seasons and there was no the most climate comfortable city in Gansu in whole year. The most human climate habit comfortable cities were Wuduo,Wenxian and Tianshui located on the Southeast of Gansu,where the human climate habit uncomfortable period was only one to two months and human habit climate comfortable periods were five to six months. The next group of human habit comfortable cities located in the Eastern of Gnasu,Middle part of Gansu,where human climate habit uncomfortable periods were three months and human climate habit comfortable periods were five months. The human climate habit uncomfortable periods were three to four months and human climate habit comfortable periods were five months in the cities that located in Hexi corridor. The degree of human habit climate comfortable in the cities on Gannan plateau was very poor. The most human climate habit comfortable period was only one month in the city which located in Gannan plateau below 3000 meters above sea level and there was no the most climate comfortable period in the city located in Ganna plateau over 3000 meters above sea. It also showed that the degree of human habit climate comfortable was superior in summer and the climatic comfortableness grade was over six except the citis located in Ganna plateau. The degree of human habit climate comfortable in winter was poor and the climatic comfortableness grade was below zero except Lanzhou and the cities located in the Southeastern of Gansu. The degree of human habit climate comfort-ability remained in same level in the most cities and the climatic comfortableness grade was over three.更多还原
